Plant Health (Growth Regulators, Biologicals, etc.), Medium Yield
Soybeans were planted in 30-inch rows at 142,500 seeds/ac in Kingsbury Co. on May 21, 2022. During planting, Vitazyme biostimulant was applied in-furrow at 13 oz/acre to four 80 ft. wide strips. Soybeans were harvested on September 25, 2022, and yield analysis was conducted on the middle harvest pass from each treated strip. The field was classified into two different yield zones, which were medium (35-55 bu/ac) and high (>55 bu/ac). This report evaluates medium yield zones. UAV imagery was collected on August 09, 2022, and an NDVI map was generated for plant health assessment across the field.
The Vitazyme in-furrow application had no significant effect on soybean yields (90% confidence interval) since the difference between treatments was less than 3.6 bu/ac (Figure 1 & Table 1). This product had better results in Brookings (+2.0 bu/ac) and Codington (+3.24 bu/ac) Counties in 2023. NDVI differences between treatments could not be detected. Additional trials with this product are needed in the future.
